cigarette ,will have a much milder taste, especially ufpon first lighting the cigarette when' some o the products of combustion of the match-are liable to be drawn into the smokersinouth. The underlying object ofthe present invention .is the production of.-

such a cigarette, and a method and means for making the same. With this and other objects not specifically mentioned in view, the inventigin consists in a cigarette so made and in a method and certain constructions and combinations for making the same which will be hereinafter fully described and then specifically set forth in the claims hereunto" appended.

In the accompanying drawings, which form a: art of this s ecification and in which like characters of re erence indicate the same or like parts, Fig. 1 is a front elevation, partly broken'away and in section, of a device constructed in accordance" with the invention and so operative in connection with a cigarette machine of the continuous rod type; Fig. 2 is a a sectional side elevation of the structure shown in Fig.1; and Fig. 3 is a sideelevation of a cigarette embodying the product Branch-ofthe invention. In carrying the invention into efiect, there is provided a filler of the usual type, and a filler enclosing wrapper of the usual type but having perforations providing for intake of 40 air between the burning end of the cigarette and the -mouth of the smoker to cool and rarefy the smoke, and thus give the cigarette a milder taste. There is further provided a methodfof making such a cigarette which consists in enclosing filler within a wrapper, and thereafter perforating said wrapper. And

. when the improved cigarette is to be made on a cigarette machineof the continuous rod type, there is provided. the usual gigarette 6o rod guide, and means for perforat ng the 1927.. Serial no. 184,498.

wrapper of said rod in said guide. Theelements of such a device may be varied in construction within the scope of the claims, for the specific device selected to illustrate the invention is. but one of numerous possible concrete embodiments .of the same. The in-' vention therefore is not to be restricted to the precise details of the structure shown and described, nor indeed to the specific method described.

While it is possible to perforate the wrapper of the improved cigarette before the filler is enclosed therein, it is preferable (forwell known economic reasons)- to make the cigarettes in machines'of the continous rod ty r.

and to perforate the wrapper after the fil er is enclosed thereinand the rod is thus formed, for the reason that perforating the paper be- .fore the filler is enclosed therein would so weaken it-that it would be more liable to tear 7 at the perforations when passing through the rod forming, pasting and sealing mechanisms.

Referring to the drawings, the reference characters 3, 4;, 5, 6, 7, 8 and 9 respectively indicate the frame, the shaft, the cutter arm, the circular cutter, the rod guide, the vcigarette rod and the ledger plate all constructed and operating in a well known manner.

- At the proper distance from the face of the ledger plate 9, so as to be iust .within one cigarette length, the perforators 10 and 11 are .slidably mounted in a. frame 12, mounted upon or forming a part of the guide 7, the inner face of each .perforator being studded with a gang of pins 13, which are so'graduated in length that their points form circular surfaces fitting, when brought into perforating position, around the cigarette rod 8, the two gangs of pins acting upon opposite sides of the cigarette rod. The perforating devices partake of the usual reciprocat' movement of the cigarette rod guide 7 an they come into action when the guide is moving at the same speed as the cigarette rod.

To the arm'5 is fastened, b means of a sleeved pivot 14, an adjustable 15 which. is pivoted to an arm 16 on a shaft 1 7 su ported in a bearing bracket 18 bolted to t e under side of the frame 3. To the shaft 17 is attached a lever 19, one arm of which is forked i v forated zone;

and engages a pin 20 carried by the lower perforator 11. The other arm of the lever 19, by an adjustable link 21, is connected to a forked lever 22, pivoted'on the frame 12 and engaginga pin 23 carried by the upper perforator '10. .By the means just described, alternate approaching and retreating movements of the two perforators, with respect to the cigarette rod, are produced.

As the cutter 6 moves downward to cut the cigarette rod 8, the link 15 attached to the arm 5 pushes down the arm 16," thereby turning the shaft 17 in a counter-clockwise direction, when viewed as in Fig. 1. This motion of the shaft 17 causes the forked end of the'lever 19 to move up and, through the link 21, causes the forked end of the lever 22 to move down, thereby simultaneously bringing the pins 13 of the perforators 10 and 11 into engagement with the cigarette rod 8, perforating the same while traveling with it during the cutting periodof the cutter 6. After the cut, when the cutter 6 moves up, the perforators separate and, with the cutoff, travel in the opposite direction to the cigarette rod until they again engage with the latter a cigarette length away from their former point of engagement. v

In Fig. 3, which illustrates a cigarette constructed in accordance with the invention, 8 indicates the cigarette generally; BE indi-' cates the burning end; PZ- indicates the per-.

and ME indicates the month end of the cigarette. The suction produced by the smoker, which draws smoke from the burning end of the cigarette through the same, also draws air through the perforations in the perforated zone. The inflowing air cools and rarefies the smoke and gives the cigarette a milder taste.

\Vhat is claimed is: i
